HARRY HEATH AND AUGUST J. MOTTLAU, OF FAR ROCKAWAY, NEW YORK.

VENTILATOR BLOWER FAN.

Application filed August 17, 1920. Serial No. 404,195.

To all whom it may concern:

Be it known that we, HARRY H. HEATH, a

' citizen of the United States, residing at Far Rockaway, in the countyof Queens and State of New York, and AUGUST J. MoTrLAU, a subject oftheKing of Denmark, residing at Far Rockawaygin the county of Queens andState of New York have invented certain new and useful Improvements inVentilator Blower Fans, of which the following is a specification.

' This invention relates to deflector fans of the type adapted to sendan upwardly and outwardly directedflow of air, and has for its object toprovide adjustable means for varying the direction of said flow.

It is of course understood that the fan may be directed upwardly ordownwardly or i in other directions, and-that the adjustable 'means isused to direct the flow of air.

Other objects of the invention will appear asthe description proceeds;and while herein minute details of the invention are-disclosed, theinvention is not limited to these, sincev many and various, changes maybe made without departing from the scope of the invention as claimed.

In the accompanying drawing showing by way of example, two of manypossible embodiments 0f the invention, a

Figure 1 is a central Vertical section partly in elevation of one formof the device;

Fig. 2 is a similar fragmental view of a' detail thereof; and

Fig. 3 is a side elevation of another form ofthe invention.

Each'of thetwo forms of our invention comprise a vessel 10 receiving atemperature changing element such as a heating unit 11 (Fig. 3) orwater, ice, disinfecting, odorizer or the like (Fig. 1), in said vesselover which rests an axially vertical approximatclycylindrical housing 15open at both ends and provided with spacing legs 16 resting in saidvessel and holding the drum spaced from said element 11 or 12. A bracket18 fixed diametrically across the drum carries a motor 19 fixed inthemidpart of said drum and havinga vertical shaft 20 carrying a fan 21 onits upper end to provide an upward draft of air.

In the device of Figs. 1 and 2, rods 24 carry a cylindrical cage 25coaxial just above said fan and provided with vertical side slits 2G 2),an inner annular groove 27 intersecting said slits, a lower axial smoothbore 28 and an upper axial threaded bore .29, said bores receiving athreaded manipulating adjusting spindle 30 having a smooth lower portion31 in said bore 28 and a threaded portion 32 in said threaded bore 39.An actuating collar rest 35 fast on said spindle 30 is formed with arounded annulus 36 about opposite said groove 27. A ring spring 39 insaid groove 27' carries tilting pieces 40 adjustably radially pivoted onsai 1 ring and projecting inwardly and outwardly from said slits 26 andprovided at the outer ends with lower inclined faces 42' and at theinner ends with rounded notches 43 receiving said annulus. Upwardl andoutwardly inclined flaring deflector eaves 45 have their lower endssecured to said inclined faces, at such an angle that alternate leavesare staggered and out of contact with each other to prevent rattlingfromvibration and are slightly overlapping.

By rotating the spindle 30 the annulus 36 is moved up or down thuschanging the inclination of the tilting pieces .and the leaves carriedthereby, and eonsequentlychanging the flare of the approximately coreshaped deflector formed by said leaves as a whole, as shown by thedotted and solid lines of Fig. 1.

Instead of a core shaped deflector Fig. 3 shows a-deflecting cowl hingedat its rear part 51 to the upper edge of said housing and provided witha downward extension ear 52 provided with an opening in which isreceived an adjusting screw 53 passed through said openin andhavingthreaded engagement with sai housing and also having an outer bandengaging said ear.

The weight of the cowl yieldably holds the car 52 against the head 54whereby the angle of the cowl may be adjusted, as shown by the dottedhead 54.

The operation of the device is very simple. It is merely set where itsuse is desired, as

in a room on a table, or other support, and

and solid lines, by. turning the the electric current turned on. If ahorizontally directed flow of air is desired, the leaves are adjusted asin the solid lines or to a more nearly horizontal position. If it bedesired that the current go mostly up, the position of the dotted lineis taken.

The heating or cooling element may be used or omitted depending upon thestate of the weather and the desire of the user. The form of Fig. 1 ispreferable for the middle of a room or table or where people are groupedaround the fan. lhe form of Fig. 3 is suitable for the side, end orcorner of a room or table on where one or several persons are seated atone side only of the device or where some prefer more or less breezethan others. Manv other uses will readily suggest themselves.

Having thus described our invention, we claim:

1. A device comprising a fan to provide an upward draft; a support inthe field of said fan; and outwardly inclined deflector leavesadjustably pivoted to said support; and a single rotary spindle operablewith a single hand for adjusting all of said leaves in unison.

2. A device comprising a housing; a fan therein to provide an upwarddraft; a support on said housing coaxial in the field of said fan; andoutwardly inclined deflector leaves adjustably pivoted to said support;and a single rotary spindle operable with a single hand for adjustingall of said leaves 111 unison.

' I 3. A device comprising a shallow vessel;

a temperature changing element in said vessel; an axially verticalapproximately cylindrical'housing open at both ends, disposed over andspaced from said element; a motor in said housing and having a verticalshaft; and a fan on said shaft constructed and driven to draw air in atthe bottom of said housing, and to pass it in contact with said elementand the motor and discharge it at the upper end of the housin 4. Adevice comprising a shallow vessel; a temperature changing element insaid vessel; an axially vertical approximatelv cylindrical housing, openat both ends, disposed over and spaced from said elen'ient: a motor insaid housing and having a vertical shaft; a fan on said shaftconstructed and driven to draw air in at the bottom of said housing, andto pass it in contact with said element and the motor and discharge itat the upper end of the casing; and a deflector at said upper end.

5. A device comprising a shallow vessel; a temperature changing elementin said vessel; housing open at its upper and lower part, disposed overand spaced from said element; and a fan in said housing constructed anddriven to draw air in at said lower part, across said element anddischarge it at said upper part.
